[0003] Some cars will have the company name or logo hot-stamped on the air intake grille. However, as the air intake grille is a large structure with an uneven surface, it is generally hot-stamped by hot embossing or heat transfer. Existing hot-stamping devices for air intake grilles, such as an air intake grille hot-stamping device with patent publication number CN220242745U, require manual removal of the air intake grille from the hot-stamping device during use, which may cause burns to the staff during the removal process. Summary of the Invention

[0004] The present invention aims to solve the technical problems mentioned in the above background technology and proposes the following technical solutions: A complete set of hot stamping equipment for an air intake grille includes a workbench, an air intake grille clamping device, a rotating base for the clamping device, two air intake grille placement brackets, and a hot stamping device. The workbench is a semicircular structure. The two air intake grille placement brackets are respectively mounted at both ends of the workbench. The hot stamping device is located in the middle of the workbench. The air intake grille placement brackets include two bracket bases and a fixed bracket. The hot stamping device includes a hot stamping seat, a hot stamping paper placement bracket, and a heating device. The hot stamping seat is fixedly mounted on the workbench. A heating device mounting groove is provided in the middle of the hot stamping seat. The heating device is located in the heating device mounting groove. The hot stamping paper placement bracket is mounted above the heating device mounting groove. The rotating base of the clamping device is installed on one side of the workbench, and the rotating base of the clamping device includes a frustum structure and a lifting base. The frustum structure is fixed above the lifting base, and the air intake grille clamping device is installed on the frustum structure. The air intake grille clamping device includes a bracket, a telescopic structure, a top plate, a clamping bracket, a lifting motor and a connecting rod structure. The bracket is fixed on the frustum structure, and the clamping bracket is installed below the bracket. A first circular hole and a second circular hole are respectively provided on the bracket and the clamping bracket. The first circular hole and the second circular hole are concentric. The lifting motor is located above the first circular hole, and the telescopic mechanism passes through the first circular hole and the second circular hole at the same time. The telescopic structure includes a fixed sleeve and a telescopic rod, and the telescopic rod is threadedly connected to the fixed sleeve. One end of the fixed sleeve is connected to the lifting motor, and one end of the telescopic rod is connected to the top plate. The left and right sides of the top plate are respectively connected to connecting rods. Sliders are provided on both sides of the clamping bracket, and the slider is slidably connected to the clamping bracket. The slider is a ring structure, and the other end of the connecting rod is connected to the slider. The two ends of the connecting rod structure are respectively connected to the slider and the clamping bracket.

[0005] Preferably, the fixing bracket is a "T"-shaped structure.

[0006] Preferably, the two ends of the clamping bracket are thick at the top and narrow at the bottom.

[0007] Preferably, a rubber pad is provided on the fixing bracket.

[0008] Preferably, the bracket includes a fixed bracket, a sliding bracket and two limit brackets, the first circular hole is located on the sliding bracket, a thread groove is provided at one end of the sliding bracket, a motor fixing groove is provided at one end of the fixed bracket, a rotating motor is provided in the motor fixing groove, the rotating motor is connected to a screw, and the screw is connected to the thread groove; The limiting bracket is located at the periphery of the fixed bracket and the movable bracket, and limiting slide grooves are set at the upper and lower ends of the periphery of the movable bracket. A limiting slider is set below one end of the limiting bracket. The limiting slide groove is slidably connected to the limiting slider, and the other end of the limiting bracket is fixed on the fixed bracket.

[0009] The beneficial effects of the present invention are: 1. By providing an air intake grille placement bracket and an air intake grille clamping device to clamp the air intake grille, it is possible to avoid manually placing the air intake grille on the hot stamping workbench, thereby avoiding the risk of burns during manual operation.

[0010] 2. By setting up a connecting rod mechanism and a top plate, and connecting the top of the connecting rod mechanism to the slider, and the slider to the top plate, when the connecting rod mechanism is inserted into the gap of the air intake grille, it can move the top plate toward the air intake grille, and at the same time the connecting rod mechanism bends laterally. The connecting rod mechanism will eventually support the air intake grille at the bottom, and the top plate will press against the air intake grille to complete the clamping work. This clamping method avoids the situation where the air intake grille is clamped off or bent by conventional clamping.

[0011] 3. By installing a rubber pad on the air intake grille bracket, it can effectively prevent the air intake grille and the air intake grille bracket from being damaged due to squeezing and friction.

[0012] 4. By setting the bracket into a retractable structure, the air intake grille and the hot stamping paper can be aligned before hot stamping to adjust according to the air intake grille of different models and sizes, avoiding the situation where the hot stamping device can only serve one model and fixed size of air intake grille, which can reduce production costs.

The workbench 1 is a semicircular structure. The two air intake grille placement brackets 4 are respectively mounted on both ends of the workbench 1. The hot stamping device 5 is located in the middle of the workbench 1. The air intake grille placement bracket 4 comprises two bracket bases 4-1 and a fixed bracket 4-2. The hot stamping device 5 comprises a hot stamping seat 5-1, a hot stamping paper placement bracket 5-2 and a heating device 5-3. The hot stamping seat 5-1 is fixedly mounted on the workbench 1. A heating device mounting groove 5-11 is provided in the middle of the hot stamping seat 5-1. The heating device 5-3 is located in the heating device mounting groove 5-11. The hot stamping paper placement bracket 5-2 is mounted above the heating device mounting groove 5-11. The rotating base 3 of the clamping device is installed on one side of the workbench 1. The rotating base 3 of the clamping device includes a frustum structure 3-1 and a lifting base 3-2. The frustum structure 3-1 is fixed above the lifting base 3-2. The air intake grille clamping device 2 is installed on the frustum structure 3-1. The air intake grille clamping device 2 includes a bracket 2-1, a telescopic structure 2-2, a top plate 2-3, a clamping bracket 2-4, a lifting motor 2-5 and a connecting rod structure 2-6. The bracket 2-1 is fixed on the frustum structure 3-1. The clamping bracket 2-4 is installed below the bracket 2-1. A first circular hole 2-11 and a second circular hole 2-41 are respectively provided on the bracket 2-1 and the clamping bracket 2-4. The first circular hole 2-11 and the second circular hole 2-41 are concentric. The lifting motor 2-5 is located above the first circular hole 2-11, and the telescopic mechanism 2-2 passes through the first circular hole 2-11 and the second circular hole 2-41 at the same time. The telescopic structure 2-2 includes a fixed sleeve 2-21 and a telescopic rod 2-22. The telescopic rod 2-22 is threadedly connected to the fixed sleeve 2-21. One end of the fixed sleeve 2-21 is connected to the lifting motor 2-5, and one end of the telescopic rod 2-22 is connected to the top plate 2-3. The left and right sides of the top plate 2-3 are respectively connected to the connecting rod 6. Sliders 7 are set on both sides of the clamping bracket 2-4. The slider 7 is slidably connected to the clamping bracket 2-4. The slider 7 is a ring structure. The other end of the connecting rod 6 is connected to the slider 7. The two ends of the connecting rod structure 2-6 are respectively connected to the slider 7 and the clamping bracket 2-4.

[0019] Preferably, the fixing bracket 4-2 is a "T"-shaped structure.

[0020] Preferably, both ends of the clamping bracket 2-4 are thick at the top and narrow at the bottom.

[0021] In actual operation, S1, the staff places the air intake grille to be hot stamped on the air intake grille placement bracket 4 on the left, with the side to be hot stamped facing downward, and then puts the hot stamping paper into the hot stamping paper placement bracket 5-2, and starts the heating device 5-3 to heat the hot stamping seat 5-1; S2. Start the clamping device rotating base 3. First, raise the clamping device rotating base 3 and the air intake grille clamping device 2 located on the clamping device rotating base 3 using the lifting base 3-2. Then, rotate the air intake grille clamping device 2 to just above the air intake grille using the frustum structure 3-1. S3. The lifting base 3-2 descends, and the air intake grille clamping device 2 descends accordingly. Then, the position of the connecting rod mechanism 2-6 on the air intake grille clamping device 2 is adjusted by rotating the frustum structure 3-1 so that it can be inserted into the gap of the air intake grille when descending. S4. When the connecting rod mechanism 2-6 is inserted into the gap of the air intake grille, the lifting motor 2-5 starts to work. The lifting motor 2-5 rotates the fixed sleeve 2-21, causing the telescopic rod 2-22 threadedly connected to the fixed sleeve 2-21 to move downward, and the top plate 2-3 connected to the telescopic rod 2-22 moves accordingly. During this process, the top plate 2-3 will press against the air intake grille, and the slider 7 connected to the top plate 2-3 will also move downward. The connecting rod mechanism 2-6, one end of which is fixed to the slider 7, is fixed at the bottom. When the top end moves downward, it will bend laterally. During the bending process, the connecting rod mechanism 2-6 will support the air intake grille from the bottom. S5. As the top plate 2-3 continues to move downward, the air intake grille will eventually be clamped by the top plate 2-3 and the bent connecting rod mechanism 2-6; S6. After the air intake grille is clamped, the frustum structure 3-1 rotates to move the air intake grille to face the top of the hot stamping seat 5-1, and then the lifting base 3-2 descends to fit the area of the air intake grille that needs to be hot stamped onto the hot stamping paper.

[0022] S7. After the hot stamping is completed, the lifting base 3-2 rises and the frustum structure 3-1 rotates, rotating the air intake grille to the right air intake grille placement bracket 4, and then the motor 2-5 rotates in the opposite direction, the top plate 2-3 moves upward, and the connecting rod mechanism 2-6 becomes straight, so that the air intake grille is no longer clamped, and then the staff can remove the air intake grille from the air intake grille placement bracket 4.

[0023] Example 2 Reference Figure 5 The difference between this embodiment and the first embodiment is that a rubber pad 8 is provided on the fixing bracket 4-2. The rubber pad 8 can effectively prevent the protective paint from being damaged due to squeezing and friction between the air intake grille and the air intake grille placement bracket 4.

[0024] Example 3 Reference Figure 6 , this embodiment differs from the first embodiment in that the bracket 2-1 includes a fixed bracket 2-12, a sliding bracket 2-13 and two limit brackets 2-14, the first circular hole 2-11 is located on the sliding bracket 2-13, a thread groove 9 is provided at one end of the sliding bracket 2-13, a motor fixing groove 10 is provided at one end of the fixed bracket 2-12, a rotating motor 11 is provided in the motor fixing groove 10, the rotating motor 11 is connected to the screw 14, and the screw 14 is connected to the thread groove 9; The limiting bracket 2-14 is located at the periphery of the fixed bracket 2-12 and the movable bracket 2-13, and limiting grooves 12 are set at the upper and lower ends of the periphery of the movable bracket 2-13.
